AMPICILLIN SODIUM vs VEETIDS '500'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
VEETIDS '500' (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis. It has activity against both gram-positive and gram-negative bacteria.
1-2 g IV/IM every 4-6 hours for serious infections; maximum 12 g/day.
1 tablet (500 mg) orally twice daily for 7 days.

Terminal elimination half-life ~1 hour in healthy adults; prolonged to 2–5 hours in renal impairment (CrCl <10 mL/min) and up to 7–20 hours in anuria; neonatal half-life 2–4 hours.
4-6 hours (prolonged in renal impairment; requires dose adjustment if CrCl <30 mL/min)
Approximately 90% renal excretion via tubular secretion and glomerular filtration; small biliary excretion (<10%); fecal elimination negligible.
Renal: 60-80% unchanged; biliary/fecal: 15-25% as metabolites
